SANITARY CLOSET.

Specification of Letters Patent.

Patented Sept. 14, 1909.

Application filed January 16, 1909. Serial No. 472,604.

with the accompanying drawings in which Figure 1 1s a perspectlve viewof a closet exemplifying my invention: Fig. 2 a plan of thehinge-mechanism; and Fig. 3 a perspectlve new of the hlnge-mechanismshown dissected.

In the drawings :1, indicates a closet bowl, of ordinary construction:2, the flush tank, illustrated as of the low-down type:

3, the flush pipe leading from the tank to ing the hinge-eyes relativeto each other, re 5 gardless of the closeness of the fit ofthe shanks ofthe. hinge-eyes in the receiving perforations of the bowl: 9, thehinge-pivot, in the form of a bar extending from one hinge-eye to theother: 10, the pivot journals j on the ends of the hinge-pivot, thesejournals passing through the hinge-eyes and outwardly some distancebeyond them: 11, the

seat-hinge-eyes, rigidly secured at the rear edge of the seat and havingeyes engaging the journals 10, preferably exterior to the fixedhinge-eyes 5: rigidly secured at the rear edge of the seat and havingeyes engaging the journals exterior to the seat-hinge eyes 11: 13, stiffstuds projecting outwardly from the opposite ends of tie-bar 7 in theplanes of oscillation of the seat-lifting levers 12, which levers occupya position to the rear of these studs when the seat is in elevatedposition: 14, buffer sleeves, as of rubber, secured upon the studs 13:15, weights upon the free ends of seat-lifting levers 12 and serving toex- 12, seat-lifting levers emplify means by which the seat isautomatically turned to upward position: 16, a valve-operating leverprojecting rigidly rearward from hinge-pivot 9, its rear end beingadapted for connection with the flush-valve of the apparatus in anyusual or suitable manner: and 17, a toe projecting forwardly from thevalve-operating lever in position to be depressed when the seat isbrought down upon the bowl.

The seat is normally held in elevated position by the weights 15, incase automatic lifting means be employed for the seat and if weights beemployed as such means. hen the seat is depressed, then its rear underportion comes in contact with toe 17 and elevates the-free end of thevalve-' operated lever, and when the seat is released and returns tovertical position, the valve operating lever drops and operates theflush valve. When the seat is elevated to vertical position, by theautomatic lifting mechanism, or by hand in case there is no suchmechanism, the levers 12 come in contact with the buffers 14, thuscushioning the motion of the seat and arresting it in proper uprightposition without the necessity for any buffer or arresting stop to makecontact with the upper face of the seat. The hingepivot 9 is a solidintegral structure extending from end to end of the hinge and, inconjunction with the tie-bar 7 makes the hinge a very substantialstructure well able to. withstand the lever-like strains brought upon itby the seat.

It will be apprehended that the levers 12, rocking on the same axis withthe seat need not be rigidly secured to the seat, though such securingis preferable, and it is also preferable that these levers be formedseparate from the hinge-eyes 11, as distinguished from being formedintegrally with them. The illustration shows them as being separatelyformed.

In the closet illustrated the seat action is automatic and thecushioning and arresting of the seat is independent of any buffer exceptthat furnished at the hinge. If the weights and their stems be removedfrom arms 12 then the seat will not be automatically lifted to fullvertical position or to any extent except as efiected by the toe 17acted upon by the valve-operating lever, but still the levers 12 andbuffers 14 will serve as a cushion and arrest for the seat when it isturned up by hand, and this consideration will apply even if the seatoperating lever and its toe be absent; in short, the buffer and arrestfor the seat is at the hinge. If, however, the arms 12 be entirelyremoved then the cushioning and arresting quality of the hinge is lostand a buffer and arrest must be provided in some usual manner, as at theface of the tank, if of low down type, or on the flush pipe or wall if ahigh tank be employed. But, regardless of whether automatic seat liftingmechanism be employed, and regardless of whether the bufiing features ofthe hinge be employed, the peculiarly substantial self-bracing qualitiesof the hinge remain and insure the proper relationship of the hingeparts to each other.

I claim 1. A sanitary closet comprising, a hinge axis a tie-plate torest on the closet bowl underneath said axis, hinge-eyes projectingupward from the tie-plate and rigidly secured to the bowl, an integralhingepivot extend ing through said hingeeyes and outwardly beyond thesame, and seat-hinge-eyes mounted on the outwardly projecting portionsof said hinge-pivot, combined substantially as set forth.

2. A sanitarycloset comprising, a hinge axis a tie-plate to rest on thecloset bowl underneath said axis, hinge-eyes projecting upward from thetie-plate and rigidly secured to the bowl, an integral hinge-pivotextend ing through said hinge-eyes and outwardly beyond the same,seat-hinge-eyes mounted on the outwardly projecting portions of saidhinge-pivot, a valve-operating lever mounted for oscillation on the axisof said hingepivot, and a toe projecting forwardly from saidvalve-operating lever and adapted to be depressed by the rear portion ofthe seat when the seat is pressed down, combined substantially as setforth.

3. A sanitary closet comprising, a hinge axis a tie-plate to rest on thecloset-bowl underneath said axis, hinge-eyes projecting upward from thetie-plate and rigidly secured to the bowl, an integral hinge-pivotextending through said hingeeyes and outwardly beyond the same,seat-hinge-eyes mounted on the outwardly projecting portions of saidhinge-pivot, studs projecting outwardly from said tie-plate, bufferscarried by said studs,-and levers pivoted on the outer ends of saidhinge-pivot and having rigid connection with the seat and adapted toengage forwardly against said buffers when the seat is in uprightposition, combined substantially as set forth. a

4. A sanitary closet comprising, a hinge axis a tie-plate to rest 011the closet-bowl underneath said axis, hinge-eyes projectingupward fromthe tie-plate and rigidly secured to the bowl, an integral hinge-pivotextending through said hinge-eyes and outwardly beyond the same,seat-hinge-eyes mounted on the outwardly projecting portions of saidhinge-pivot, studs projecting outwardly from said tie-plate, bufferscarried by said studs, levers pivoted on the outer ends of saidhinge-pivot and having rigid connection with the seat and adapted toengage forwardly against said buffers 'when the seat is in uprightposition, and seat-lifting devices connected with said levers andadapted to lift the seat to upright position, combined substantially asset forth.

5. A sanitary closet comprising, hingeinembers supported by the bowl, atie-bar, buffers having rigid connection with said tie-bar,seat-hinge-eyes pivoted to said hinge-members, and levers having rigidconnection with said seat-hinge-eyes and adapted to engage said bufferswhen the seat is in upright position, combined substantially as setforth.

6. A sanitary closet comprising, a bowl, a seat, a pair of hinge-eyesrigidly secured to the bowl, a pair of hinge-eyesrigidly secured to theseat, a hinge pivot bar extending through all of the hinge-eyes, and avalve operating lever projecting rigidly rearward from said hinge pivotbar and having a toe projecting rigidly forward from said hinge pivotbar, and adapted to be acted on by engagement with the rearward portionof the seat bottom, combined substantially as set forth. Y
